Abstract

ABSTRACT Low productivity in seaweed farms in the Philippines is due to issues ranging from lack of training, weather damage, and prevalence of pest and diseases. This study sampled 63 small-scale seaweed farmers in Ipil, Zamboanga Sibugay, as part of a development project. Technical Efficiency (TE) scores were calculated using the two-stage double bootstrap Data Envelopment Analysis (DEA) approach to investigate the causes of inefficiencies and external factors affecting small-scale production. Bias-corrected TE scores reveal that input use can be reduced by 55% to produce the same level of output, suggesting significant efficiency gaps. Factors such as primary occupation, number of farms, access to credit, farm location, and type of product sold had significant effect on technical efficiency. Extending government loan facilities to include seaweed farmers can lead to a reduction in inefficiency. Government initiatives to encourage seaweed farming, choosing the right farm location, and providing information can positively impact efficiency.

采用两阶段双引导DEA方法分析影响小型海藻养殖场技术效率的因素

菲律宾海藻养殖场的低生产力是由于缺乏培训、天气破坏和病虫害流行等问题造成的。作为一个开发项目的一部分，本研究对三宝颜西布盖Ipil的63个小规模海藻养殖户进行了抽样调查。采用两阶段双bootstrap数据包络分析(DEA)方法计算技术效率(TE)得分，探讨低效率的原因和影响小规模生产的外部因素。经偏差校正的TE分数显示，投入使用可以减少55%，以产生相同水平的产出，这表明存在显著的效率差距。主要职业、农场数量、获得信贷、农场位置和销售产品类型等因素对技术效率有显著影响。将政府贷款设施扩大到海藻养殖户，可以减少低效率。政府鼓励海藻养殖、选择正确的养殖场位置和提供信息的举措可以对效率产生积极影响。
